cut is a bit annoying in that even if you set the delimiter to a space, it takes all spaces as delimiters. It'll find a large bunch of empty fields in that input...

You could use cut -cN-M with appropriate values to pick a fixed-width field, or awk '{print $5}' to print the fifth field (awk takes multiple spaces as as one delimiter). Or you could use something like sed -e 's/^.*A[[:space:]]*//' to remove everything up to the (last) A, along with the following white space...

  • Thanks for the responses! I'll give them a try at work tomorrow. Sorry about the screenshot, but this is my first time on here. – Jason Estes Jan 25 '18 at 23:52
  • Thanks guys! The awk command worked very nicely for my needs. – Jason Estes Jan 31 '18 at 1:33

A simple awk command:

awk '{print $NF}' file

will print the last field ($NF) of the file.
